information from WSDOT

The Washington State Department of Transportation will close both directions of SR 99 between South Spokane Street and Valley Street from 10 p.m. Friday, Aug. 22, until 5 a.m. Monday, Aug. 25. Crews will reopen SR 99 south of the Battery Street Tunnel just before the Monday morning commute; however, the highway will remain closed through the tunnel to Valley Street until 5 a.m. Wednesday, Aug. 27.

“We need Seattle commuters to plan ahead for this closure,” said Dave Sowers, deputy administrator for the WSDOT Alaskan Way Viaduct Replacement Program. “The section of 99 we’re closing Monday and Tuesday is shorter in length than what we’re closing that weekend, but it has the potential to create longer backups and delays both on city streets and I-5.”

Seahawks traffic considerations
· Northbound SR 99 will be open from South Royal Brougham Way and southbound SR 99 will be open from Columbia Street until midnight Friday, Aug. 22, for traffic related to the Seahawks’ preseason game.

Why a four-day closure is needed
· It will take four days for contractor crews working for WSDOT to demolish and replace the section of SR 99 over Broad Street. This new section of the highway will become part of the permanent connection between the SR 99 tunnel’s north portal and a new surface street section of Aurora Avenue North.
· Four days are also necessary for crews to reroute the water and sewer lines underneath SR 99 near Harrison Street.
· During the weekend portion of the closure, contractor crews will replace 81 damaged or cracked concrete road panels that comprise the SR 99 lanes between South Spokane and South Holgate streets. They will also repair an expansion joint at the northbound SR 99 exit to Seneca Street.

Driver tips

· Leave early or delay your trip to avoid traveling during peak commute periods in the morning and afternoon.
· Delay or reschedule discretionary trips.
· Consider telecommuting.
· Take King County Metro during off peak hours and plan for reroutes on buses that use SR 99, or share a ride in a car or vanpool.
